Current　closed-loop　control　technology　is　introduced　into　monostable　permanent　magnet　(PM)　contactor　in　this　paper.　There　is　current　closed-loop　control　presented　in　detail,which　adjusted　coil　current　in　real-time　to　control　the　dynamic　processes　directly.　Full-bridge　circuit　is　transformed　to　realize　the　controlof　the　coil.　In　addition,　the　simulation　model　of　contactor　with　control　is　built.　The　control　circuitry　is　designed　in　Multisim　and　the　dynamic　model　of　contactor　based　on　magnetic　circuit　method　is　designed　in　LabVIEW.　Connecting　LabVIEW　and　Multisim　it　realizes　co-simulation　of　dynamic　model　and　control　module　of　contactor.　This　paper　analyzes　the　principle　of　control　circuit　and　property　of　contactor,　considering　the　inductance　changing　of　circuitry　and　the　effect　of　PM.　In　conclusion,　the　control　module　has　many　advantages　such　as　compactness,　high　reliability,　Core　collision　and　contact　bounce　during　pick-up　and　no　power　consumption.　The　experiments　are　performed　to　verify　control　module.　©　2019　by　International　Academic　Publishers　Ltd.
